Description
Instant Search adds a fast, real-time search bar to any WordPress site. Your visitors see results the moment they start typing, no page reload, no waiting. It also includes live voice search powered by the browser’s built-in Web Speech API, making your site more accessible without any third-party services or API keys.
It works with any theme and is built to work great with WooCommerce shops, blogs, portfolios, directories, and any site with custom post types.
Drop the shortcode [instant_search] anywhere: in a page, a post, a widget, or your theme’s header template, and you have a working search form with instant Ajax results.
Voice Search for WordPress
Voice search is no longer a nice-to-have. Mobile users expect it, and users with disabilities depend on it. Instant Search is one of the only WordPress search plugins that includes live voice search for free.
It uses the browser’s built-in Web Speech API. The visitor clicks the microphone icon, speaks their query, and results appear instantly. Voice search works on Chrome, Edge, Safari, and most modern mobile browsers.
Why Instant Search?
It’s lightweight, free, and self-hosted, your search queries never leave your server.
Unlike the default WordPress search, Instant Search shows results as you type in a dropdown, so visitors find what they need without ever leaving the page. And with voice search built in, users on mobile or with accessibility needs can speak their query instead of typing it.

WooCommerce Search That Actually Works
The default WooCommerce search is basic, it only matches post titles. Instant Search goes further:
- Search products by SKU, so customers who know the part number or model code find the right product instantly
- Results appear in a dropdown as the customer types, so they never leave the page they’re on
- Choose between grid and list layouts for product results
- Works with variable products, simple products, and any WooCommerce product type
Search Analytics
Instant Search includes a built-in analytics dashboard that shows you what your visitors are searching for. See the top 20 search terms at a glance. No Google Analytics required, no tracking scripts, no cookie banners. The data stays on your server.
